I have a script where the mouse drags an item. However, I want that script to be able to round to the nearest 10.

For example;
10 by 10: Correct
260 by 570: Correct
10 by 15: Incorrect

Here is the script:

func dragItem():
	isDragging = true
	
	var mousePos = get_global_mouse_position()
	mousePos = mousePos.floor()
	self.set_position(mousePos)
	print(mousePos)

What can I do to make sure it always rounds to the nearest tenth?

GDScript has the handy stepify(float s, float step) function. For example:

var mousePos = get_global_mouse_position()
self.set_position(Vector2(stepify(mousePos.x, 10), stepify(mousePos.y, 10)))

In Godot 4 this is now a function called snapped()
